To a ZZ whom it may concern:

, Be it known that we, DEELVILLE E. PETERS, Gnoncn H. FATE, and ALBERTF. MILLER, citizens of the United States of America, residing at thecity and county of Denver and State of Colorado, have invented new anduseful Side-Turnln Wipers for rapping the Side Edges of Boxes withGummed Blanks, of which the following is a specification.

hold the. edges in and neatly and quickly glue them to the interiorsurfaces of the boxes. I.

Second. To provide a simple high speed, reliable and artistic wrappingand covering mechanism for folding the edges of blanks over into andadhesively wrapping them against the inside surfaces of the open edgesof boxes. ."Ve attain these objects by the mechanism illustrated in theaccompanying drawings, in which:

Fig.10 is a vertical sectional view on the linelO10 of Fig. 1; and

Figs. 11 and 12 are views respectively of a tight wrap and a loose wrapblank.

Similar letters refer to similar parts throughout the several views.

Referring to the drawings:

The mechanism illustrated in Figs. 1 and 2 illustrates our invention. Inthese views, as well as in all of the other views, the numeral ldesignates the turn-in wipers.

Our side turn-in wiper mechanism is arranged to receive bones betweenthem that vary in sizes from about 1% inches wide by 3 inches long toabout 12 inches :wide by about 20 inches long.

The boxes adapted to be wrapped are paste board boxes either with stayedor unstayed corners, and the blanks .or labels are preferably made ofthin, smoothly calendered white plain paper cutout into a form,-as shownin Figs. 11 and .12, and they are coated with gum, either wholly or partially on one side, as shown in Figs. 11 and 1:2.

These blanks or labels are adhesively wrapped or covered around andagainst the outside surfaces ofv the boxes before they are submitted toour present side turn-in mechanism,1and they are ted'either by hand orby any suitable automatically operating mechanism between our sideturn-in mechanism, each box having the edges of the blank projectingabove the edges of the box far enough to be folded over into and gluedagainst the interior surfaces or" the opposite sides of the boxa Aftereach box has had its open side edges wrapped, it is discharged from ourpresent side wrapping mechanism.

Just before and instantly after our side turn-in mechanism, the boxesare subjected to end turn-in. mechanism which acts cooperatively withour herein described side t11m-inmechanisnr to prop'erly wrap the openedges of each box This end turn-in mechanism does not, however, form apart of our presentinvention,.-and it is not either illustrated or deingapplication for a patent for a box wrapping machine, Serial. No. 59.860,nled November 5, 1915.

These side turn-in wrappers 1 comprise preferably strips of metal whichare secured to a slide block 2, by clamping strip 3,

that is clamped to the'head block by a clamping .bolt 4;, that isthreaded into the slide block 2. This head block is provided with arearward extending portion which terminates in a cross bar the terminalends of which are arranged to form trunnions having rollers 6 that bearin the yokeshaped ends of two arms 7. r

The detail construction and arrangement of this side turn-in mechanismis as follows: To the top of the table on opposite sides of itslongitudinal center and at equal distances from it we secure two headblocks 8,

which support the side turn-in mechanisms.

The side turn-in mechanisms of these two head blocks face each other,and as they are exactly alike a description of one will suflice forboth.

Each head block consists of a base portion 9, that is slidably mountedto be moved in a horizontal plane in a transverse slideway '10, formedin the table, and a vertically movable chuck block 11, that isvertically adjustable upon upwardly projecting standards 12 that areformed on the base 9. The standards are yoke-shaped and are providedwith guideways and each chuck block is provided with a capped lugportion 13, that is slidably mounted in the guideway of the standard. Athreaded rod 14 is rotatably mounted at its upper end in a bushing 15 atthe top of the standard and threads down through the lug 13 of the chuckblock, its lower end resting in a bearing 16 in the adjacent end of thebase 9. The threaded rod is adapted to receive a wrench to turn'it toraise or lower the chuck block which has a vertical movement on thestandard sufficient to allow it to be adjusted to all heights or depthsof boxes the machine will wrap. This chuck box extends down through aslot in the table, when adjusted for boxes of slight depth, and it isadj ustably movable up and down to accommodate boxes of differentdepths, and is fixed in adjusted positions by its cap 17, which can beclamped tightly to thestandards. The chucks face the opposite sidesofthe box that is to be wrapped (see Fig. 1), and the opposing sidemembers 18 of each chuck are each provided with a semicircular slideway19, and in each pair of slioeways is mounted a segmental block 20, whichtherefore travels in a semicircular path and is moved in this path by acombination of link and lever members which are constructed and act asfollows:

The segment block is of the form shown in Figs. 8 and 9, and is providedwith a depending bifurcated lug 21, to which one end of a link 22 ispivoted. The lower end of this link is providedwith an oblong slotand'is' pivotally connected through this slot by a pin 23 to the upperend of a vertically a reciprocable bar 24:, which is slidably mounted ina guide 25 that is formed on a depending portion of the headblock.

The lower portion of each of the bars 24; is provided with an adjustablecollar 26, that rests on a springQT that is housed in a socket 28 thatis attached to a cross bar 29,which cross bar is given a verticalreciprocating movement by a forked lever 30, to

which it is bolted, and which is operated by a cam 31, which is securedupon the main driving shaft The upper end of the forked lever 30 movesin a guideway of a 1 standard 33, which is bolted to the bed plate.

The upper portions of the bars 24 are square,

but the lower portions thereof are rounded and extend through thesprings 27, and sockets 28, to allow for vertical adjustments tocorrespond with adjustments vofthe head blocks to fit boxes of differentheights.

Each bar 2 1 has a rib portionila, that has a cam curve at its upper endthat engages a roller 36, that is mounted on the depending member 37 ofa rock arm. This rock arm comprises a long hub 7 that is pivotallymounted on a pin 38, that extends through it and the sides of the chuck,the depending member 37, and the two arms 7, spaced a short distanceapart and extending upward, the end of each of which terminates in amounted on opposite sides of the end por tion of the sliding block 2,which is reciprocally mounted in a 'slideway 40 formed in the top of thesegment block 20. Arms "1 turn-in blade 1, as shown by Figs. 2 and d.

The side turn-in blades are of a length corresponding to the insidelength of the boxes being covered.

Along the front face of each chuck we secure a bar 44, against which theupper edges fork 39, in which lie the rollers 6 which are I mpasse-4o ofthe-'sides' of the bo'xe's bear, when the turniniblades bend theextended portions 7 of the 1 sides of the blank over against the innerThrough these plugs passes -asquare rod -4:8,

the ends of which (are rounded and enter bushings in the sides 7 of thetable. A threaded rod -49 vextends parallel with and adjacent t'o thesquare rod 18, and upon-the endportions of the threaded rodare screwedfollowers '50, comprising vhub members hat in arms 51-, the outer endsof which are :bi urcated, and straddle the annularly grooved ends "ofthe plugs 46. Thus by turning the crank handle 52,on the end of the theaded rod l9,'the1said rod is rotated, and the he'ad blocks aremoved,inward or out- Ward in their slideways 10.

The object of threading the plugs 46 to the bushings is as follows: Whenthe bones pass from the first into the second stage position, the headb'locks stand in such positions relatively to each other that the boxesmay pass readily between the loars 44, Without touching them, but afterthey have reached their proper position it is necessary that their sidesshould he engaged by the said bars 44, and to accomplish this a lightinward movement is-giy'en to each head block by turning the square rodby which the plugs are tur-nechand "as the-plugs when turned by thesquare rod are held against lateral movement by the followers 50, thehead blocks are "thereby ;moved in or out according to the "direction ofrotation of the plugs. The square rod is turned inthe following-manner:A cam disk is mount ed on the main driving shaft 32, and has a cam 54:,which engages a roller on one member of a double 'crank arm, which issupported in a bracket 56, thatris'bolted to the bed plate of themachine. The other arm connects With the lower end of a connecting rod58, the upper end of which is'pivotally attached to a lever 59,Whi'eh'is mountedon the adjacent end of the square {shaft It will thusbe seen that the cam 54, imparts =movement to the connecting rod 58, bywhich the lever 59 is rocked andthe shaftturned.

The chucks having been adjusted with their guide strips in operativerelation to re ceive a box and-blank-betweeii them,'the segment blockand the sliding block operate to cause thes'ide turn-in blade 1 to turnin the upwardly projecting side edges of the 'of a quarter of circle inthe semi circular fblalnk intothe interionand against the inside siri'aces of the box in the tollowing 1111211111 61 W hen ithe bars 124 areraised by the cam 31, the cam :curves at the upper end of the bars firsten ga ge "the-rollers 236 of the rock arm, which causes the lower endsof the rock arms to swing-out :andtheirupper end to push the slidingblocks Q'fonward toward theb'oli, which causes' theside turnin blades tomove horizontally "forward and engage the projecting edges of the blahk,and in moving forward they barely clear the top side edges of the boxthen as they reach the end of their inward stroke the pins at the stop0f the "bars 24: have by this time moved up with the *bars-to the upperend of the slots in the links 322, which connect the bars with thesegment blocks 20, and thus li ft the segment blocks, causing them toino'vein an are curved slid'eways of thec huoks, which causes thesliding blocks and the turn-in blades to tilt upward into verticalpositions, and as the blades tilt "over the side edges of the box theybend the edges of the blank over into the box and against its insidesurfaces and the blades press the blank tight-1y against the insidesurlaces of the box when it swings into a cfulland a trifle more than arun vertical position, which brings a decided side pressure "of theblades 1, against the inside of the box, thus firmly pressing the edgeof the blank against the inside surface of-the box, the turning-inblades thus rolling over the edge of the-box and pressing flat againstits insidesurface, the sides of the b0X with the turned-in blank beingpressed between the said blades and the bars 44c.

When thesegnient blocks move upward in their curved slideways 19, in thechucks, they lift the rollers '6, of the sliding block 2, ou tof theyoke ends 39, of the arm 7, and *sW-ing'thein up into such a verticalposition as is necessary to cause the finger blade to press and thusglue the edges of the blank against the inside surface of the oppositesides of the box.

Our present invention provides a positively operative side turn-inmechanism and one that is easily and quickly adjusted to bo'xesof thedifferent sizes that it is made receive, and While We have illustratedand described the preferred construction and arrangement of ourinvention, We do not wish to be limited to the construction andarrangement shown, asinany'changes might be made Without departing fromthe spirit of our invention.
